Distance 18.2 km
Highest point2,743 m
Lowest point1,617 m
The hike starts at the Untersee lake Arosa and leads to the Isel, across the river and deeper into the wild valley (Welschtobel). The hills on both sides are steep and one might also observe chamois, deer and ibexes. Once at the Ramoz hut (a non-attended SAC hut) it might be wise to enjoy a break before the path ascents to the Erzhorn saddle. As of here surefootedness and head for heights is required. Also the ascent demands high concentration. As soon as the tricky passage is over the path continues downhill to the Älplisee lake. Your feet will love the cool down in the icy water. During the summer you might even enjoy a swim. After the Älplisee lake the trail leads to the Schwellisee lake and finally arrives back to Arosa.
An overnight stay in the Ramozhütte is an unforgettable experience. (Self-catering hut, reservation required)
The trail across the Erzhorn saddle is an Alpine hiking trail and marked with white/blue sign posts and requires surefootedness and no fear of heights. Please follow the rules and signposting. You will find more helpful tips under Hiking Info.
